摘要
RPA calculations, based on the cranked shell model, are performed for superdeformed Dy-152 in which five excited bands have been found recently. We show that characteristic features of the observed dynamical moments of inertia are well accounted for by explicitly taking the octupole correlations into account. Importance of the interplay between rotation and octupole vibrations is stressed, and it is suggested that one of the observed excited bands might be a collective octupole vibration built on the superdeformed yrast band.
